At the time of the Restoration, Charles II seemed to give every indication that his first and most important alliance as King of England would be with Spain. Contemporary circumstances were such that this policy would have been logical, and Charles's behavior in 1660 encouraged Europeans to expect it. Yet, within a year of his return, Charles had not only failed to forge the Spanish alliance, he had entered into a marriage-alliance with Spain's rebellious province, Portugal. The events surrounding this apparent change of attitude encouraged the Spanish government and others to misinterpret Charles's intentions. At best, the new King was seen as a weak monarch who was lured into a comfortable dependence on Spain's natural enemy and self-appointed protector of Portugal, Louis XIV, King of France. At worst, Charles was accused of duplicity, of falsely courting Spain while maneuvering into an anti-Spanish coalition being constructed by France. In both interpretations, Charles was believed to have been seduced by the French King very early in his reign. The Portuguese alliance raises the question of the nature of Charles's foreign policy immediately after the Restoration. What were his relationships with France and Spain? What did he intend by the Portuguese alliance? The key to understanding his behavior lies in his treatment of Spain, and from an examination of his Spanish policy in light of the controversial alliance, it is possible to see both reason and consistency in Charles II's initial diplomacy.
